We've been using this filter regularly ever since 2010, when we bought our house. It works great and if you forget to change it at 6-months or whatever, the water/ice cube SMELL (sulfur) will give you A HINT ! I'm glad they still make this item, and will continue to use it. Very easy to install, no flow problems or leaks at all.

Have been using this undersink filtration unit for more than three years. The water has absolutely no off color or taste. The filter lasts longer than six months due to an additional in-line filter in the basement. All in all fits my needs.
